Sealing efficiencies for butterflies are 99.50%
to 99.85% without seal air and 100% with
seal air.
Guillotines, although more costly, provide
the least static pressure loss and assurance of
100% sealing efficiency or “man-safe”
isolation with a solid plate blade.
Sealing efficiency for a guillotine damper
ranges from 99.75% to 100%.
Closing times are faster with poppet valves
(1/2 to 1 sec) versus butterflies (1 sec) and
guillotines (10 sec min - size dependant)
Poppets do not seal as well as butterfly or
guillotine dampers with sealing efficiencies
to 99.75%.
Poppets do not survive system upsets and
fires as well as butterfly and guillotine
dampers.

Sealing efficiencies for rectangular butterfly
dampers range from 99.00% to 99.75% and
100% with seal air.
Multi-blade louver dampers offer sealing efficiencies from 98.00% to 99.50% and 100% in
double louver configurations (w/seal air).
Guillotine dampers provide sealing efficiencies
from 99.75% without seal air and 100% with
seal air.
Operating times range from ½ to 1 sec. for
louvers, 1 sec. for butterflies, and 10 sec min
and are size dependant for guillotines.
Louver dampers are more costly than
butterflies but less than guillotines.
Static pressure loss is minimal with guillotine
dampers and greatest with louver dampers.
Louver dampers are available in parallel or
opposed blade configurations for improved
flow control where sealing efficiency is important but improved control is also desired.

Radial Vane
Flow Control of gas in round ducts is best
accomplished with round opposed-blade and
radial vane blades.
Butterfly dampers provide excellent control of
static pressure and volume in mid-range, but
less than adequate low-flow control when
compared to opposed-blade louvers.
Radial vane dampers are preferred for control
of gas entering centrifugal or radial fans.
Flap diverter dampers are designed to control
flow during startup of waste heat equipment.
Positioning devices with analog or digital
inputs are available to maintain reliable flow
control on most damper configurations.

Opposed-blade louver dampers provide
superior control of static pressure and

Parallel-blade dampers installed on centrifugal
fan inlets divert gas thus reducing fan horse
power and electrical power input.

OPTIONS & ACCESSORIES
Dampers can be provided with a wide array of options and accessories designed to improve
performance, automate operation, provide system feedback, increase safety or create redundancy for
critical applications. The following is a sampling of devices to consider when specifying or purchasing
equipment:
materials of construction
Dampers can be manufactured of many materials including carbon steel, stainless steel or nickel alloys
such as Inconel, Hastelloy, Monel, fiberglass, etc. Matching the adjacent ductwork is the preferred
approach. In some instances, internal refractory lining is incorporated in our scope of supply.
drives
Dampers can be operated utilizing manual handwheels or actuator
chain falls. Automated actuators include electric, pneumatic and
hydraulic. Electric actuators can be supplied in all customary
voltage requirements. Pneumatic and hydraulic actuators can be
supplied with the necessary solenoids and accumulators. Damper
control systems are designed to assume the closed, open or last
position upon loss of source power or signal.
Pneumatic or
Hydraulic
Solenoid
Pneumatic or
Hydraulic Drive
Electric
Drive
positioners and positioner feedback
Control dampers require an input signal to position the blade(s) correctly. Signals are either electric (4-20
mA), pneumatic (3-15 psi or 3-30 psi) or digital. Positioners are a required accessory for controlling the
location of the blades beyond full, open or close. Refer to the Engineering Design Data, Curves & Specifications on pages 15 & 16 for additional information on blade orientation versus flow or pressure drop.
5
linkage
The styles of linkages are fixed and adjustable. Fixed linkage employs hardened steel pivots
with thin-film PTFE (Teflon®) bushings. Linkage has lever arms pinned to the blade shafts.
Adjustable linkages utilize turnbuckles to allow field re-adjustment of blades at operation
temperature or over time.
Opposed Blade
bearings
Bearings can be standard ball bearings, high-cycle ball bearings or adjustable
UHMW (Ultra High Molecular Weight) and graphite sleeve bearings.
Ball bearings are typically used when process temperatures do not exceed
500NF. Graphite sleeve bearings are ideal for 90 degree rotation and
temperatures exceeding 500NF.
packing
Packing glands are mounted separately from bearings to allow maintenance
Bearings
of shaft packings and eliminate improper loads on bearings or packing. The number
of compressive bolts and packing gland material is dependant on the operating conditions.
Other accessories to consider:
• Limit or proximity switches
• Position transmitters
• Access doors
• Electric enclosures
• Conduit trim
• Personnel guards
• Lock-outs

Louver
Louver dampers employ fast acting single or dual rows of rectangular blades, mounted
within a rigid frame for installation in round and rectangular flanged ducting. Louvers are
particularly well suited for flow modulation, bypass, isolation and backflow prevention
applications.

blanking plate and offer superior isolation of flue gas applications containing heavy particulate
loads and are ideal for tight shut off applications.

Diverter
Diverter dampers are available in three configurations: butterfly tee, multi-louver and flap diverter. Tee
diverter dampers extend the capabilities of the butterfly damper design by combining two butterfly dampers
into a common wye or tee fitting, primarily for isolation/bypass applications. In a wye configuration,
diverters can allow synchronized actuation of each blade for the purpose of splitting and modulating flow.
Flap diverters are designed to provide up to 100% sealing efficiency
while minimizing heat loss and pressure drop. They are ideally
suited to isolate waste heat recovery units on gas turbines.

This curve provides a sealing efficiency
comparison between various types of
dampers with different seal options. A
sealing efficiency of 100% generally
requires a pressure-assisted sealing system.
Pathway manufactures several designs
including the Patented model 362 and 365
butterfly dampers, Pathway model 150C
double-louver damper, and model 222,
230, and 266 guillotine dampers. Sealing
efficiency for all damper styles can be
improved with available options.
Guillotine w/Seals
conclusion
Use butterfly dampers when cost is the primary consideration. Selecting seal options is a very inexpensive
way to achieve better isolation. Select guillotine dampers in cases where pressure loss is a major consideration. Should 100% isolation be required, select one of Pathway’s many models with the help of a factorytrained application engineer.

This curve illustrates the advantages and
disadvantages of each damper type for
static pressure control. Butterfly dampers
for round ducts and opposed blade
dampers for rectangular ducts provide
excellent static pressure control. At midrange blade positions, static pressure can
be effectively controlled. This is not the
case with parallel blade dampers where
pressure control can only effectively occur
approaching closed position. Parallel
blade dampers are better suited for prespin of gas entering centrifugal fan inlets
where gas flow direction favors fan
efficiency improvement.
percent flow versus blade position
This curve illustrates the advantages of
opposed blade dampers and butterflies for
fine flow control. These produce nearlinear flow control characteristics as a
function of blade position making them
ideal for use with positioning devices.
Parallel blade dampers provide acceptable
flow control exceeding 20-30% full flow.
Turbulence produced by parallel blade
dampers must be accounted for in the
design of duct systems

100%
This curve illustrates the differences in open
flow area percentage as a function of blade
position. From 0 to 30 degrees, butterflies and
opposed blade louvers change very little in
open area compared with parallel blade
louvers. Small changes in open area equate to
more precise low-flow control during startup
of process systems. From 65 degrees to 90
degrees, parallel blade louvers exhibit better
high-flow control since rate of change in open
area is less as a function of blade position.

conclusion
Use opposed blade dampers for control of static pressure or flow in rectangular ducts. Parallel blade dampers
should be used for isolation and flow diversion such as for the inlets of centrifugal fans. Butterflies can be
used for control as well as isolation where they are especially adept. Specialized applications for flow control
include radial vane fan inlet dampers and diverter dampers.
